Ignition Coil UF349x4 4-Pack for Nissan/Infiniti - Reliable Fit

In this review the MAYASAF UF349x4 4-pack ignition coil is evaluated for drivers who need a direct replacement for failing coils on compatible Nissan and Infiniti models. The bottom line: it delivers an exact fitment and strong spark performance for the listed vehicles, making it a sensible, cost-effective repair option for owners confronting misfires or weak ignition. Installation is straightforward for many, and the coils are built to meet or exceed OEM standards, so they appeal to DIY mechanics and independent shops looking for dependable replacement coils.

Key Features

• Exact Fitment: Matches factory fit for specific Infiniti and Nissan years and models so no modification is required during swap-out.
• Premium Quality: Constructed for durability with high electrical resistance and corrosion resistance to maintain performance under stress.
• Strong Spark: Designed to deliver a robust spark to the plugs, helping correct cylinder misfires and restore smooth running.
• Easy Installation: Direct replacement form factor allows technicians and competent DIYers to install without special tools or rewiring.
• OEM Compatibility: Cross-referenced with many compatible part numbers so it aligns with common replacement part expectations.

Who It's For

The UF349x4 is best for owners of compatible Nissan and Infiniti models who need to replace one or more failing ignition coils, including those driving Altima, 350Z, Maxima, Murano, Pathfinder, Frontier, Armada, Quest, Xterra, I35 and QX4 vehicles within the listed years. It is suitable for independent shops and DIY mechanics who prefer parts that match OEM dimensions and use straightforward swap procedures.

It is less appropriate for users who require manufacturer-backed dealer parts for warranty reasons or for vehicles outside the listed fitment years. Also, if a buyer plans frequent resale of components, anecdotal concerns about resaleability suggest caution for that use case.
